IllustrationWhen vehicle gets wet, knock sensor trips and puts the vehicle in limp mode. Making it very dangerous to drive since everything is underpowered and makes it hard to get up to speed, shift, etc.

This is a known issue within these new Hyundai N cars and Hyundai is completely clueless. It’s a “p1326 code” that pops up after a carwash. Whenever the knock sensor gets wet it automatically puts the car into limp mode at highway speeds and it’s very hazardous. There has to be some type of cover that Hyundai has to put over the knock sensor or this will continue to happen to us while it’s a brand new car.

While driving through heavy rain on the interstate Friday night the CEL came on and the vehicle immediately lost power and went I to a limo mode causing my car to rapidly lose speed while on the interstate. Restarting the vehicle did nothing. I called the closest Hyundai dealer and they said " oh yeah the N models do that a lot in the rain or through carwashes, it triggers false knock sensor codes, you can try to get a parts store to clear the code or you can come in tomorrow and we will clear the code." I then got a parts store to clear the code and the vehicle has been fine since. I did a quick internet search and apparently this is very common and lots of owners have this happened multiple times a year and the dealer has no fix or intention of a fix
